  • Patent number: 11123131
    Abstract: A tool (16) for the coagulation and dissection of biological tissue including a counter-bearing (35) that has at least one recess (37) open toward the outside and/or one or more hollow chambers (63). The recess (37) or the hollow chamber (63) is configured to provide a force/path elasticity characteristic curve with a plateau-like region II, V, during compression and reexpansion. The path section x in which the elasticity characteristic curve indicates the plateau II, IV preferably is as long as the tissue to be dissected is thick, and is, for example, in the range of 0.2 to 1.5 mm. As a result, the force exerted on the tissue during the cutting operation remains substantially constant in the effective work region.

  • Patent number: 11090076
    Abstract: A surgical instrument includes a shaft portion which at least partly houses an axially movable cutting element. A handle receives the shaft portion. A trigger element for the cutting element is movably arranged on the handle. The instrument also includes a coupling mechanism which converts a rotation of the trigger element into an axial movement of the cutting element with the interposition of a pinion. The coupling mechanism is designed such that the rotation of the trigger element produces a rotation of the pinion about the central axis thereof and additionally an axial movement of the central axis.

  • Patent number: 11013555
    Abstract: Devices and methods for delivering fluid to tissue during ablation therapy are described herein. An exemplary device can include an elongate body having an inner lumen, outlet ports, and an ablation element configured to heat tissue. A flow resistance of the elongate body can increase along a length of the elongate body containing the outlet ports in a proximal to distal direction. This can be accomplished by, for example, varying outlet port size or relative spacing, decreasing a cross-sectional area of the inner lumen through which fluid can flow using a flow diverter or tapered inner lumen sidewalls, or limiting a ratio between a total area of the outlet ports and a cross-sectional area of the inner lumen. Adjusting flow resistance of the elongate body can provide more uniform fluid distribution or a desired non-uniform distribution.

Some embodiments disclosed herein pertain to methods of treating tumors, systems used for irradiating tissue and tumors with electromagnetic radiation, components and devices of that system, and kits for providing systems used for irradiating tissue and tumors with electromagnetic radiation. In some embodiments, the system provides sub-ablative infrared radiation that is absorbed by nanoparticles. In some embodiments, the nanoparticles absorb the radiation converting it into heat energy. In some embodiments, though the infrared radiation itself may be sub-ablative, the heat energy generated by the nanoparticles is sufficient to cause thermal coagulation, hyperthermia, and/or tissue ablation.
